In order to enable or inactive all or part liquid injection apparatus 120, this device is configured to relative to the enabling of some liquid injection apparatus 120 of the blast velocity control recorded, stops using and/or expulsion pressure, such as, by means of microcontroller 170 and interface 101.
In this way, such as, if the wind speed recorded is greater than the second predetermined air speed value, then all liq injection apparatus 120 of can stopping using.
Such as, the liquid injection apparatus 120 being positioned at polylith photovoltaic panel center can therefore only be enabled.The expulsion pressure of some liquid injection apparatus 120 can also be adjusted according to wind speed.
Such as, when wind is stronger, spray larger cooling fluid drop preferably by reduction expulsion pressure.
But when wind-force is lower, inventor determines, spray tiny cooling fluid drop preferably by increase expulsion pressure.
In another embodiment of the present invention, this device is configured to pass performing in steps described in Fig. 4 and carries out thermoregulator method to plurality of plates 110.
In the first step (S300), such as, temperature sensor 130 is utilized to record at least one temperature of at least one piece of photovoltaic panel 110.Such as, microcontroller 170 control survey frequency can be passed through.
In second step (S310), such as, utilize air velocity transducer 140, record polylith photovoltaic panel 110 expose wind speed wherein.Such as, microcontroller 170 control survey frequency can be passed through.
In the 3rd step (S320), record polylith photovoltaic panel 110 expose wind direction wherein.For this reason, temperature-adjusting device can comprise the instrument measuring wind direction extraly, such as wind vane etc.Such as, microcontroller 170 control survey frequency can be passed through.
In the 4th step (S330), such as, determine that at least one liquid injection apparatus 120 starts by microcontroller 170 to spray or stop to spray.
In order to enable or inactive all or part liquid injection apparatus 120, this device is configured to the wind direction relative to recording, and such as, by microcontroller 170 and interface 101, additionally controls enabling and/or stopping using of some liquid injection apparatus 120.
More specifically, the wind speed that can be recorded by consideration and the wind direction recorded are stopped using and are exposed to some liquid injection apparatus 120 maximum in wind.
Therefore, by considering the wind speed recorded and the wind direction recorded, only can enable and being exposed to liquid injection apparatus 120 minimum in wind.
In another embodiment of the present invention, carry out thermoregulator method to plurality of plates 110 to be explained by all the following steps:
If additional the first predetermined value being greater than physical parameter of the measured value of the physical parameter at-plurality of plates place, then make at least some liquid injection apparatus 120 start and spray; And,
If additional the second predetermined value being less than or equal to physical parameter of the measured value of-physical parameter, this second value is less than the first predetermined value of physical parameter, then make at least some liquid injection apparatus 120 stop spraying.
In an example, physical parameter is corresponding with the sun light quantity that plurality of plates place receives.
Such as, in this case, if the working temperature of photovoltaic panel 110 is higher, and a sheet of cloud starts through photovoltaic panel, thus reduction solar radiation, then at least some liquid injection apparatus 120 can be made to stop spraying, because the temperature of plate itself can decline naturally because sun light quantity declines.For this reason, temperature-adjusting device can comprise the instrument of the sun light quantity that measurement receives extraly, such as pyranometer etc.
In another example, physical parameter is corresponding with the electricity that at least one block of plate produces.
In this case, such as, if the working temperature of photovoltaic panel 110 is higher, and such as, because the solar radiation that photovoltaic panel receives reduces, so the electricity that inverter 150 produces reduces, at least some liquid injection apparatus 120 so then can be made to stop spraying, such as, to save liquid, because plate does not produce a large amount of electricity at this moment.
In another example, physical parameter is corresponding with the electric current of at least one electric device be operably connected at least one block of plate and/or the measured value of voltage.
In this case, such as, can measure at the one or more measurement points combined with following content:
-ground and/or the ground wire at least one block of plate;

Equally, such as, if the temperature of cooling fluid is higher relative to the temperature of photovoltaic panel 110 before spraying, such as, at about 30 DEG C, such as, the temperature of photovoltaic panel 110 is at about 25 DEG C, so at least some liquid injection apparatus 120 can stop spraying, because the level attempting the temperature of polylith photovoltaic panel 110 to be reduced to the temperature be significantly less than before cooling fluid is sprayed is proved to be invalid.But, when the temperature of cooling fluid is quite low relative to the temperature of photovoltaic panel 110, then makes at least one liquid injection apparatus 120 start and spray.

If the additional setting temperature less than or equal to cooling fluid of the measured value of the ambient air temperature of-plurality of plates, then at least some liquid injection apparatus 120 is made to stop spraying.
In this case, such as, if the ambient air temperature of at least one piece of photovoltaic panel 110 is lower than the setting temperature of liquid, then at least some liquid injection apparatus 120 can be made to stop spraying, because cooling fluid has the risk of freezing.For this reason, when only having setting temperature higher than liquid of air themperature around, just make at least some liquid injection apparatus 120 start and spray.
